HPHA/HIHS General Specifications
"Adapter Style": The "Harrington Permanent Adapter", "HPHA", threads onto the male steamer nozzle and is secured permanently to the nozzle with (2) setscrews. A Storz Spanner Wrench is required for cap removal to prevent unauthorized tampering.
The "HPHA" consists of two primary parts, a "Storz Adapter" and a "Storz Cap", connected together with aircraft cable to prevent cap loss.
The Storz adapter is made of Forged 6061-T6 alumimum and is hard anodized in accordance with Mil-A-8625, Type 3, Dark Gray. The Storz adapter has a "metal face seal" on the Storz side and a 4.5" Female NST thread with a rubber gasket on the opposite side. The Storz adapter is equipped with (2) setscrews in the NST female thread for permanent installation on the male hydrant nozzle.
"Integral Style": The "Harrington Integral Hydrant Storz", "HIHS", replaces the male steamer nozzle and is secured permanently into the hydrant body with a setscrew. A Storz Spanner Wrench is required for cap removal to prevent unauthorized tampering.
The "HIHS" consists of two primary parts: a "Storz Nozzle" and a "Storz Cap", connected together with aircraft cable to prevent cap loss.
The Storz nozzle is made of forged aluminum (hard anodized in accordance with Mil-A-8625, Type 3, Dark Gray) and cast brass, connected together with our patented method to make an Integral Storz nozzle.
The Storz cap consists of two primary Parts: an "outer ring" (known as a "Storz Clamp Fitting") and a "center-cap" functionality. Both the outer ring and the center cap are made of Forged 6061-T6 aluminum and are hard anodized in accordance with Mil-A-8625, Type 3, Dark Gray. The center-cap is equipped with a Storz gasket, sealing against the metal face of the Adapter. The center cap is specially machined to make cap removal difficult. Cap removal requires a Storz Spanner Wrench. This modification prevents unauthorized cap removal and tampering by unauthorized personnel.
Harrington Integral Hydrant Storz and Harrington Permanent Hydrant Adapters are made in the USA.
Additional notes, regarding "Storz-Lok" on a permanent Storz adapter and/or Storz Cap:
With the NFPA 1963 Standard relative to "nonthreaded connections (Storz)", hose couplings have been manufactured "with Storz-Lok" since 1993. In other words, all 4" & 5" Storz "Hose Couplings" have been provided with "Storz-Lok" since 1993. The intention of a "Storz-Lok" is to prevent accidental disconnection of Storz connections. Each lock is designed to withstand a force of "300 lb x ft" (NFPA 1963 6.3.6). NFPA 1963 also indicates that the (Storz) cap is exempt from the standard, as stated in 6.3.1. The application of a "Storz-Lok" on any part of the Storz "permanent hydrant adapter" could be potentially hazardous if any damage should occur to the locking assembly during the life of the fire hydrant. This includes accidental or intentional damage.
